Yes, judging from the graph the Spitfire lost pre-patch 30km/h for each 1000 m of altitude (from 530 at 4000 to 500 at 3000). At the same pace it will end up with 400km/h at 0 m (= 250mph).

Post-patch it seems to be slightly less (Maybe I just want so see that), maybe 25km/h for each 1000m. This would result in 415km/h (=260mph).

Of course that won't help much against the 460/490 km/h of the Bf 109.

IMHO the base speeds are not that badly implemented compared to historical values. However the WEP, which was historically available for the Bf 109 only for take-off and up to 1-1.5km gives the in-game Bf 109 a huge speed advantage.
